HENRY L. DISMER, OF DAVENPORT, IOWA.

l MACHINE FOR WRAPPING BED MATTRESSES.

Application filed March 1G, 1925.

To all whom t may concern:

Be it known that HENRY L. Dienen, a citizen of the United States, residing` at Davenport, in` the county of Scot-t and State of Iowa', has invented certain new and uscful Improvements in Machines for lVrapping Bed Mattresses, of which the following is a speciication.

My invention relates to improvements in machines for wrapping bed mattresses and similar bulky objects.

The objects of my invention are to pro'- vide a simple mechanically constructed and easily operable machine for holding and wrapping mattresses, with mea-ns to permit the easy removal thereof after being wrapped and tied.

l attain these objects by the mechanism illustra-ted in the `accompanying drawings, in whicln- Figure 1 is a plan view; Fig. 2 is a side .elevation thereof; Fig. 3 is an enlarged seetional detail showing the fastening of the bed sheets to the angle irons; Fig. 4 1s a detail of the mainshaft and Figure 5 is an enlarged detail in cross section of the mow able main shaft bearing on the line 3 3 of Figure 2.

My machine comprises a bed composed `preferably of metal sheets, 10, 11 and 12,

secured to angle irons, 2, 4, 5, 6, 7 and 3, supported at the foot by legs, 1 and 3, preferably composed of angle iron and stiilened by diagonal braces, 43.

The head of the bed is supported by a frame preferably composed of angle iron, with oblique upright legs, 13, 16, 17, 20. 24 and 28. The legs, 13 and 16, are stilfened by diagonal braces, 14 and 15, and the legs, 17 and 20, are stiifened by diagonal braces, 18 and 19, and the legs, 24 and 28, are like- Wise stiifened by cross braces, 49 and 50.

.A lateral brace, 48a, has one end secured to cross braces, 49 and 50, and its middle portion secured to the rib, 22, which with the angle irons 9, 21 and 23, support the curved end of the bed and its opposite end secured to the corresponding cross braces secured to the legs, 13 and 20.

I The bed of my machine has a substantially horizontal portion extending from the foot supports to the main supports and a regularly curved bed, 51, extending upwardly from that point to the highest point of the bed.

The thin metal sheets which form the bed are preferably secured to the angle Serial No. 15,077.

irons by countersunk screws or bolts a shown in Figure 3, so as to leave a` smooth surface upon which nothing can catch.

A main shaft, 337 is mounted in hearings, 32, 34 and 41, and each of these bearings is formed with a downwardly extending portion which is secured to the adjacent portion of the angle irons forming the upper portion of the legs of the main frame. (lne end of the shaft has secured to it a cranlr, 30, which is secured by a set screw, 31, and is provided with a handle, 29, by which the shaft can be turned manually.

Arms, 35 and 40, formed integral with hubs, are mounted upon the shaft over the curved portion of the bed. An auxiliary shaft, 39, is mounted in the arms, 35 and 40, one end of which being secured to the arm, 35, by loc-k nuts, 37 and 38, and the opposite end being seated in a suitable opening in the out-er end of the arm1 40. rl`hc arm, 40, has an enlarged hub formed integral there with, which extends outwardly from the body of the machine and this hub has an opening corresponding to the frceend of the shaft, which has its upper half cut away as in Figure 4.

The bearing, 41, is secured by bolts, 44,

to the upper end of the angle irons forming the legs, 28 and 24, and is hinged to the lower portion of the legs by a rod, fio that it can be placed in a. vertical position as shown in Figure 2` or in a. horizontal position as shown in dotted lines in Figure l.

In the operation of my device, the sheet of paper or material with which the mat tress is to be wrapped is first spread upon the bed, 12, and the mattress laid thereon with the upper end of the mattress and paper extending between the main shaft, 33, and the auxiliary shaft, 39. the auxiliary shaft securing them in position. By turning the crank, 30, the main shaft, 33, is re volved and the mattress and paper wound thereon and then securely tied.

The arm, 40, and its supporting angle irons, 26 and 27, are then swung outwardly and downwardly upon thel rod, 25, as a pivot, so as to leave one end of the main shaft and the corresponding end of the auxiliary shaft free. The rolled mattress can then he slid oil the main shaft and the auxiliary shaiit laterally and the machine will then be ready to insert a new mattress and repeat the operation.

The bearings, 32 and 34, should be spaced head having far enough apart to afford a firm support for the free end of the main shaft when dis engaged from its bearing', 41.

I claim:

l. A machine for folding and Wrapping mattresses comprising a bed, an extended fixed support secured to the bed, at one side thereof carrying a'pair of widely spaced bearings secured thereto, and a relatively narrow hinged support secured to the pposite side thereof, the hinged portion of said support carrying a suitable bearing, a an arm formed integral therewith revolvably mounted in the bearing of the hinged support, a main shaft having one end rotatably mounted in the bearings Y of the fixed supportjand its opposite end adapted to enter the head secured in the bearing of the hinged support when in vertical position, a fixed arm secured to the main shaft adjacent the fixed bearings thereof, an auxiliary shaft having one end secured in the fixed arm and its opposite end adapted to enter the arm of the head secured in the hinged bearings and means for rotating the main shaft secured near the fixed bearings thereof.

2. A machine for folding and Wrapping mattresses comprising a flat bed mounted adjacent a curved head, an extended fixed support secured to the bed and curved head at one side thereof carrying a pair of Widely spaced bearings secured thereto, and a relatively narrow hinged support secured to the opposite side thereof, the hinged portion of said support carrying a suitable bearing, a head having an arm- :formed integral therewith revolvably mounted in the bearing of the hinged support, a Amain shaft having one end rotatably mounted in the bearings of the fixed supportand its opposite end adapted to enter the head secured in the bearings of the hinged support When in vertical position, means secured to thel main shaft adapted to hold one end of a mattress in engagement with the main shaft While being Wrapped.

8.v A machinefor folding and Wrapping mattresses comprising a fiat bed mounted adjacent a curved head, an extended fixed support secured to the bed and curved head at one side thereof carrying a pair of Widely spaced bearings secured thereto, and a suitable support secured to the opposite side thereof, a main shaft having one end rotatably mounted in the bearings of the fixed support and means by Which the opposite end of the main shaft can be supported While Wrapping a mattress and left free when.

the wrapping is completed, means secured to the main shaft adapted to hold one end of a mattress in engagementy With the main shaft While being Wrapped. i

ln testimony whereof he aflixes hi-s signature.
